3789a13c30 Make the Dwarf macro information section optional; CellSPU's assembler 
doesn't support it. The default is set to 'true', so this should not
impact any other target backends.

ccfacfff9a Introduce two DWARF attribute extentions DW_AT_APPLE_optimized, DW_AT_APPLE_flags. 
DW_AT_APPLE_optimized flag is set when a compile_unit is optimized. The debugger takes advantage of this information some way.

DW_AT_APPLE_flags encodes command line options when certain env. variable is set. This is used by build engineers to track various gcc command lines used by by  a project, irrespective of whether the project used makefile, Xcode or something else.

llvm-gcc patch is next.

af6a3748c7 Do not use DenseMap because the iterator is invalidated while constructing types. After all there was a reason why std::map was used initially!

b71fbeb19f If multiple compile units are seen then emit them independently. In other words, do not force all DIEs into first, whatever it is, compile unit. 
Note, multiple compile unit support is not well tested (it did not work correctly until now anyway.)
